To all whom it concern:

Be it knpwnthat I, FRANK A. GATEWOOD, a citizen of the United States,residing'at Sylvan Grove, in the county of Lincoln and:

or a nut which is more .or less inaccessible and operated from a remotepoint to readilyturn the bolt or nut home or withdraw the same. Theinvention also seeks to provide means whereby the wrench may be held Iagainst operation after the nut or bolt has been loosened so that lossof the member operated upon will be prevented.

The invention is illustrated in the accomp gaged in the notches 9 andthe lever then panying drawings, in which- Figure 1 is an edge elevationof the improved wrench;

Fig. 2 is a side elevation, partly broken away, showing a locking handleor lever applied thereto;

Fig. 3 is a detail perspective view of the locking handle.

In carrying out the invention, I employ side plates 1 which are securedtogether in spaced) relation by screws or bolts 2, as clearly shown.Between the plates, I provide a train of gears consisting of end gears 3and 4 and an intermediate gear 5 meshing with both end gears whereby totransmit motion from one to the other. These gears are mounted uponaxles or shafts journaled in the side plates 1 and the end pinions orgears have their shafts or axles extended beyond one side plate, asshown at 6 and 7 respectively. The extended portions are of angularcross section whereby they may receive a socket member, indicated indotted lines at 8, or may have a crank or brace applied thereto so as tobe rotated. It will be noted that the extensions 6 and 7 are disposedatopposite sides of the wrench. In the opposite edges of the side platesadjacent the-gearr3, I provide arcuate notches or recesses 9 which aredisposed concentric to the gear and are adapted to receive the ins orstuds 10 on the sides of a locking ever or handle 11. The studs areprovided 7 as shown in Fig. 2.

on footportion 12 which is disposed approximately at a right angle to.the main portion of the lever or handle and in the concave side of saidfoot portion I form a plurality of transverse teeth 13 which are adaptedto engage the teeth of the gear 3,

In the use of the device the socketS is engaged over the extension 601'the extension 7 and then fitted to the bolt head or nut whichis :to beturned. A brace or other turning tool is applied to the other extension6 or 7, as the case may be, and rotated thereby imparting motion to the.end gear 3 or 4 which will be transmitted through the gear 5 to theother end gear. If the nut or bolt should be corroded or jammed so thatit will not turn easily, the lever or handle 11 is brought into use, thestuds 10 being enturned about the pins or studs 10 until the teeth 13engage the teeth of the adjacent gear and consequently hold the train ofgearing against movement. The wrench then becomes practically a rigidwrench, the side plates 1 and the handle 11 acting as a single lever toapply turning force to the nut or bolt.

My wrench is especially applicable to withdrawing nuts from or applyingthem to bolts which are located in corners or angles and will be foundhighly efficient. It is composed of very few parts which are very simplein their construction and consequently are not liable to get out oforder.

Having thus 3 described the invention, what is claimed as new is:

A wrench comprising a pair of side plates handle having a foot portionadapted to fit between the side plates and constructed to engage andlock the adj acent gear, andstuds on the opposite sides of said footportion of the locking handle to engage the notches in the edges of theside plates.

In testimon whereof I aflix m signajure.
